KeyManagement: Cannot lock EpochState: WouldBlock

[lacabra]

Describe the bug
The following has been observed while running the integration tests with 2 nodes:

p2p_2        | [Thu May 09 2019 20:43:41 GMT+0000 (Coordinated Universal Time)] ERROR Failed Principal node connection: -32603 - Unable to get keys: EpochStateIOErr { message: "Cannot lock EpochState: \"WouldBlock\"" }

To Reproduce
Steps to reproduce the behavior:

1. Launch the network with 2 nodes: NODES=2 ./launch.bash
2. Run the first integration test: 01_init.spec.js

The test passes, but the network output reveals an error.
It does not happen consistently, only sometimes.

Expected behavior
No error.
